If a freshwater fish is placed into a saltwater environment, is that osmosis or diffusion?

Question

Please explain

Answer 1

Osmosis is one kind of diffusion ... osmosis is the diffusion of water across a selectively permeable membrane.

So you could describe what happens in the fish's cells as osmosis (which is more specific) or diffusion (which is more general).

Answer 2

It is osmosis and diffusion.
Osmosis is when the diffusion occurs, but moves through a semi permiable membrane.
so your much better if you go with Osmosis, because it's more specific :]

Answer 3

It is torture and certain death for the fish. Both would occur.

Answer 4

both
